The V40 fragmentation grenade was manufactured in the Netherlands, and was in service in the Canadian Forces and the US Armed Forces

The V40 grenade is spherical in shape, 6.5 cm (2.5 in) high, and 4 cm ( 1.5 in) in diameter - approximately the size of a golf-ball. It has a safety pin and safety lever with a safety clip attached to the safety lever.

The steel body of the grenade has 326 squares pressed into its inside face to produce separate fragments when the explosive fill is detonated. The V40 weighed 136 gm (4.8 oz) and was issued primed from the manufacturer. Fuze delay time was four seconds. This grenade was considered lethal up to a radius of 5 metres (5.5 yards) and dangerous up to 300 m (325 yd) from point of impact. It was commonly referred to as the Mini-Frag
Due to its small size, a considerable number could be carried; but small size also made the weapon dangerous when wearing gloves, as the impact of the striker on the primer was difficult to feel. These grenades where in service from the late 1960's to at least 1984.
